Chapter 209 The Dwarf Version of the Ventilator Is Available!

Grete coughed and vomited, rinsed his mouth and wiped his face. After struggling for a while, he regained consciousness and quickly rushed back to the old dwarf. On the way, I didn't forget to pick up a spoon and collect sputum, preparing to go back for bacterial culture experiments.

——The phlegm entered his own mouth! Who knows what germs are in there! Mycobacterium tuberculosis? Streptococcus pneumoniae? staphylococcus? Or some mycoplasma? Chlamydia? Fungi?

Don't let him get infected!

Gretel hit a healing spell on himself with his backhand. He was worried when he thought about it, but it was another healing spell. His care for himself ended here: the old dwarf was obviously hypoxic just now. How he is recovering now and whether he needs further treatment will have to be confirmed with his own eyes before he can rest assured.

He rushed over and saw that Master Tarbot had been helped up and was sitting on a stool drinking water. Two dwarf priests, one on the left and one on the right, were accompanying the teacher. Seeing Grete running towards him, the priest who had been thrown [Language Comprehension] immediately jumped up and made room for him:

"Hey, thank you so much just now!"

The old dwarf also stood up slowly while holding on to the table. Grete quickly bent down to help him: "Master, let's sit outside? If you can't breathe smoothly, it's best not to sit inside. It's full of smoke..."

"No need, I'm fine like this." The old dwarf slowly smiled. Grete became anxious: "Master!!!"

"Okay, okay, I'll listen to you." The old dwarf patted the back of his hand slowly. Once, twice. The corners of his eyes were slightly curved between his white beard and white hair, and his smile was exactly the same as when their mentor was seriously ill and his disciples begged him for treatment.

After patting twice, the old dwarf let go of Gretel, took the hands of the two disciples and walked out. A large group of dwarves rushed around in the tavern, carrying tables, moving chairs, lighting torches, and waiting for the old man to settle down on the hillside outside. The refreshing mountain breeze blew in waves, and the tired face of the old dwarf gradually relaxed.

Grete sat down in front of the old dwarf. Observing carefully, the old man's lips and fingernails were no longer bruised, but his breathing was still rapid. The two dwarf priests looked on eagerly, and the one who was thrown [Language Comprehension] came closer and asked carefully:

"Mr. Pastor, is there anything you can do to help the teacher? We have done everything we can..."

"Don't smoke, don't drink, breathe more fresh air, and don't sleep in a place with poor air circulation at night." Gretel looked at them seriously:

"And take some expectorant medicine regularly to help cough up phlegm. I am not good at medicine. I will write a letter to Elder Wood. You can take the letter to Oak Ridge and ask him for medicine. And..."

And oxygen! For respiratory failure secondary to chronic lung disease and respiratory failure caused by interstitial pulmonary fibrosis, although oxygen therapy cannot cure the disease, it can effectively improve patient comfort and oxygenation!

Gretel felt around in his pocket and took out his precious little test tube and the potassium permanganate in the test tube:

"Use the gas inside as a spell-casting material, gather the same type of gas together, and put it in a bubble spell to let people breathe. Who knows this spell—or divine spell?"

The two dwarves looked at each other. They looked at Grete with blank expressions, and Grete looked at them with blank faces, like another scumbag tutoring a scumbag in solving problems. Did I not explain it clearly... Obviously when I explained it to Elder Wood, he understood it quickly?

"I can give it a try." Elder Talbot coughed a few times and suddenly spoke at the edge of the long table. The two dwarf priests turned around in shock: "Teacher!"

The old dwarf waved his hand. He looked at Gretel seriously:

"But, how do I know that the magic is used correctly and that the gas gathered here is the one in the tube?"

"Yes!" The two dwarf priests nodded. The tube is empty, colorless and odorless. Even if it takes half a day of effort, how do you know that the magic is used correctly? It’s always confusing if you can’t see the proof…

"I have a solution for this." Gretel thought for a while, continued to dig through his pocket, and took out a complete set of alchemy equipment from the space bag. On-site installation, on-site experiments, and on-site collection of a tube of carbon dioxide:

"Try this?"

The old dwarf took the test tube and concentrated on using magic to gather the gas in an empty beaker. After casting the spell, Grete lit a candle and poked it into the beaker. The candle flame did not waver, but a plume of black smoke rose up and went out quietly.

"Yes, that's it!" Grete stroked his hands. He dug out the earliest tube of potassium permanganate and carefully heated it to allow the potassium permanganate to decompose into oxygen. When the powder in the bottle turned from purple to gray-black, Grete handed it to the old dwarf and said earnestly:

"First release a bubble technique for yourself...Put the gas collected this time in the bubble technique and breathe by yourself!"

The old dwarf was doubtful. But looking at Grete's eager eyes, he still raised his hand and tried the method for himself. Soon, his face turned rosy and he let out a long breath.

"How is it? Teacher, how is it?"

"much better……"

The old man's voice was light. Grete squatted beside him and quickly added:

"It's best to inhale this gas every day. - When you use a large magic spell and feel very tired and out of breath, or when you keep coughing and can't sleep at night, it's best to inhale it. I can't say it can cure it, but it can help. People feel much more comfortable.”

The two dwarf priests nodded and almost clicked out the afterimages, one on the left and one on the right, grabbing Gretel and thanking him a thousand times. Grete thought for a while:

"By the way, it's best not to use the bubble technique. It's too small and will be inhaled in a while, and the subsequent exhaust gas will be harmful to people. It's best to put a tube near the nose, and connect a bellows behind it, one by one. Click to inject the gas. As long as there is a dedicated person to inflate the bellows, the elderly can also inhale the gas when they are tired or asleep..."

He spread out the pen and paper, brushed and drew a schematic diagram of an oxygen tube and an oxygen pump. After he finished painting he said:

"It is best not to use people to pull the bellows, as it is easy to over-ventilate. Get a mechanical transmission device at the back and push it with water or any force... For example, get a water tank to put water in, push the bellows and pull it... However, I will do this It’s no longer possible…”

"We can do this!" Both dwarf priests laughed. "Making this kind of stuff is our specialty!"

Grete pushed the pen and paper cleanly.

I give you paper and pen, Master, please draw!

A large group of dwarves started working at the same time, dividing the work and cooperating. Gretel is only responsible for calculating the tidal volume, the speed of each push and pull of the bellows, and the air supply volume. He handed over the data and went straight to bed. Early the next morning, he saw a strange-looking ventilator - or rather, an oxygen supply bellows...

At the front is a tight-fitting mask. According to Grete's requirements, two one-way valves were specially made to facilitate the discharge of exhaust gas. There is a rubber tube behind the mask. If the mask is removed, the tube can be fixed directly next to the patient's nostrils.

There is a bellows with a spring attached to the back of the pipe, and something like a water wheel is constantly rotating beside it, pulling and pushing the bellows. What drives the waterwheel is a wine barrel with a faucet——

The wine barrel is filled with clean water, and the water level is always maintained at the highest point to ensure that the flow rate and impact force remain unchanged, and the bellows can pull at a uniform speed. There is a taller and fatter wine barrel poked next to it, connected to the former through a siphon, and there is a dwarf standing next to it, pouring water into the tall wine barrel...

This... this is really a nice thing... at least it's semi-automatic...

Gretel's eyes shone and he smiled at the dwarf priest.

"This...can you make another one for me...I can use it to save other people..."

He took out his wallet. Before the bag's rope was pulled open, the palm of his hand was already firmly pressed:

"Why are you giving us money? You are our good brother. If I make something, I can still ask for your money! Wait, I will make it for you tonight!"

yeah! ! !

The dwarf version of the ventilator is here!

In the future, as long as you reach level 5, learn the oxygenation magic, or find a way to get a liquid oxygen tank, you can give people oxygen!

Great Hospital, a powerful rescue tool, is available again!
